Thin-film lithium niobate two-photon and four-photon quantum sources

Thin-film lithium niobate (TFLN) has recently emerged as an ideal platform for integrated photonics owing to its broad transparency window, superior nonlinear optical characteristics, and convenience in ferroelectric domain inversion, leading to efficient quasi-phase-matched (QPM) frequency conversion processes. In par...

Tensor-Engineered Van der Waals NbOCl2 Resonant Metasurface for Polarization-entangled Bell State Generation

Polarization-entangled photon pairs are essential resources for quantum information technologies, yet realizing compact sources with intrinsically controllable entanglement remains challenging. Van der Waals (vdW) nonlinear materials such as NbOCl2 provide atomically thin platforms for quantum light generation, yet the...
